Underpinning quantum technologies

All of the work we do involves the advancement of novel quantum technologies, with a specific focus on those based on photons. However, quantum technologies based on photons will almost certainly require an integrated optics architecture for improved performance, miniaturization and scalability.

Here at the University of Bristol, we have demonstrated high-fidelity silica-on-silicon and silicon integrated optical realisations of key quantum photonic circuits. These results show that it is possible to directly "write" sophisticated photonic quantum circuits onto a silicon chip, which will be of benefit to future quantum technologies based on photons.

This could lead to significant advances in a wide range of fields including information processing, communication, metrology and lithography as well as the fundamental science of quantum optics.
